absurd file size - autocad crashes while working

[stefano26k]

Good morning.

My name is stefano and I am new to the forum. I have a problem I've faced with a stratagem but I'd like to understand the cause. I am using autocad mechanical 2013. I attach a very simple dwg file whose size is not justified by the content or at least by what you see. in addition to the problem of size there is also the fact that it becomes difficult to work within this file because the computer tends to block, especially during the rescues and past copies. Moreover, this "virus" is contagious because if I copy from this file anything, even one line, in another file, the latter is having the same problems. I also tried to purge, I removed any filters, deleted all the drawing contained in the file, but nothing changes. the solution that I have adopted at the moment is to save the file in dxf and then again in dwg. doing this sometimes, finally the file is reduced in size and becomes manageable. this system is slow for file problems and also long because it has to be done several times but above all, serious thing, it deletes the information of the baloon. It almost seems that the file has information that I do not see and that in the various steps they are lost.
someone came across this type of problem or would you know where there may be hidden information in autocad mechanical that can hang the file?
thanks to the attention

I am not talking about mech, which I think is an absolute nonsense (my personal opinion that I have supported for years)
the only thing you can do is a _wblock of all design, yours has passed from 1.8 mb to 51kb.

I have an old version and can't open the file, but check that there are no excess line types.
give a read to this post http://www.cad3d.it/forum1/threads/...on-eliminabili?p=314643&viewfull=1#post314643

thank you, sorry but it is not clear to me the _wblock command: did you actually reduce the size? to respond to massivonweizen instead, I actually found on some drawings problems of excess lines, but not only, I also found many nested blocks that however do not get rid of with the purge command. I uploaded the macro indicated but I did not understand what the command name is to launch it.

Thank you, I'm sorry, but I don't understand the _wblock command.

_wblock = write block.
You make a block of all the drawing (Select what you need ) and expose it as a file, then an external block to the drawing.
Your square has reduced, as I have written, from 1,8 mb a 51kb.

I uploaded the macro indicated but did not understand what the command name is to launch it

is a lisp, not a macro; as you did not find the command that are three lines...
[...]once extract the file upload it with appload and launch it with p, then indicate the dictionary you want to delete:follow cast[...]

I apologize, stupid me. I managed, and it works. Thanks for the help.
Unfortunately for some drawings still remain problems especially because of blocks that are not purgable. does not exist a "explodes" command that really explodes everything, even blocks of blocks up to the last in a single blow?

excuse stefano for curiosity, and for love of precision but.......
How did you solve that?
via the wblock command indicated by almost your eponymous stefanobruno, or through the lisp that proposed you massive?? ?
